Inspection of semiconductor/electrical devicesMT type

MT type series are anisotropic conductive sheet type, which consists of soft silicone rubber and of gold-plated metal wires embedded densely into it. This type of Inter-Connector is suitable for inspecting and connecting IC packages such as BGA, QFN or SON. Since MT-4X type has 4-time metal density, it can be used to CSP. Especially, MT series are superrior in transmitting high cycle.

Offset to connecting electrode

※ Since metal wires are inclined in the direction parallel to L dim., upper and lower connecting electrodes need "offset".

Continuity resistance

Measured by 4-terminal method
The test method: the above-described drawing.

1 Electrode:
Size 0.4mm x 0.4mm
Gold plated electrode (50 patterns)
2 Test samples:
0.5mm t (Offset 0.25mm)
1.0mm t (Offset 0.5mm)
2.0mm t (Offset 1.0mm)


  • A small amount of silicone will remain on the inspected (IC package, etc.,) connected with MT-type connector.
  • When the inspected (IC package, etc.,) with soldered electrodes is pressured and welded to MT-type connector, the solder can adhere to the metal wire part of the connector.
  • When the inspected (IC package, etc.,) is pressured and welded to MT-type connector, it can be absorbed to the conncetor.
  • Attachments such as dirt, dust and the other alien substances will remarkably increase the contact resistance of the connector.
  • A cross section cut through L direction will be inclined. See the right illustration.
  • MT series Operating Temperature Range: -35~100 degreeºC.


Every item or numerical value indicated herein is measured by Shin-Etsu and out of guarantee.
The quality of the connector, which has been already assembled, is out of guarantee.
Please make sure to see about the purpose/conditions of use and practice your own test. Industrial ownership like patent doesn't guarantee the usage of the connector.
